That does look promising! I just watched the video.
It’s been said here that that is the reason why impellers have the thin strip of rubber in the circle and onto the blades…..because when they are “squished”…..it will only be that small surface area that makes total contact…..thereby reducing friction.
It’s also been said here that it’s not the best idea to “shave” impellers down to make them shorter….because in doing so you remove those thin strips. Your chosen method did not require such modification!
Great job! Sure hope it works up to your expectations.
